Lette/rs Patent A70. 87,090, dated February 23. 1869.A i I rMPRo'vnMnNT 1N SUGAR-PRESSES.

The Schedule referred to in these Letters Patent and making part-of the seme.

Tofall whom t may conce/m Be it known that I, WILLARD C. BRUSON, of the city of Chicago, in the countyof Cook, and State of Illinois, have invented a new and improved Sugar- Press; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a perspective representation of my new and improved sugar-press, the plane of longitudinal section being indicated by the line 2 2.

Figure 2 is a vertical central sectional elevation of the same.

Figure 3 is a perspective representation of the corecylinder.

Figure, 4 is a perspective representation of the follower-and the inverted perforated conical top.

Figure 5 is a top View of the follower, shown at fig. 4, with theconical plate removed.

Figure 6' is a view of the lower end of the corecylinder.

Figure 7 is a transverse section ofthe fall-leaf conductor; also, an elevation of the buttons, and a broken section of the iron frame A.

Figure 8 is a plan view of the stationary and fallleaf conductors.

The object of my invention is to provide a powerful and convenient press,by the use of which the molasses can be speedily forced out of rnush-sugar,.which term is commonly applied llto partially crystallized or granulated sorghum, imphee, muscovado, beet, maple,

and all kinds of undrained sugar.

t is well known among experienced sorghum-sugar growers, that sorghum-Sirup contains more or less vegetable albumen, which is a gummy, waxy, substance, and

when the sirnpcrystallizes, the gummy substance remains incorporated in the mush-sugar, and prevents it from draining, or the molasses from being forced out, by means of the ordinary presses, with the rapidity necessary to make the business profitable.

The common slotted or perforated pressing-boxes which'are now in use, either with or..without iine cloth, secured either outside or inside of the pressbox, separate but a small proportion of the molasses contained in the mush-sugar, as the gummy substance adheres to the cloth in a very brief time, which prevents the escape of the molasses, thus rendering the means heretofore used practically useless.

Furthermore, the requisite pressure` for separating the molasses from the mush-sugar, by means of the ordinary presses, has a tendency to force about onehalf of the molasses to the central part of the pressbox, and `there the liquid remains, whichagain eectrally defeats the separation desired.

In my invention, I claim to have obviated what-*has heretofore been the principal objection, as above menthe molasses, but forming a complete central drainage in the press-box, hoop, or cylinder, by which device a speedy and effectual separation of `liquids from all kinds cf solids may be produced.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, by referring to the above-mentioned drawings, and letters of reference marked thereon.

of iron or other suitable material, upon which rests the or groove D', extending about one-fourth the vlength of the platform B.

The conductor N is firmly secured tothe frame A.

At O is shown the fall-leaf conductor, with the necessary grooves, O and A', one end-being annexed to the conductor N, and hung to the frame A, by means of hinges, or other suitable fastenings.

The other end ofthe conductor O is held in its proper position, which is about horizontal `when in use, by one or more buttons P, which can be turned so as to allow the endof the conductor to fall down.-4 ward to a'vertical position, as shown by the dotted line J', iig. 2, when it is desired to discharge the con- .tents of the press-box Q R.

plates, the inside plate R being perforated withholes and, at the same time, allow a free escape of molasses.

The outside plate Q contains larger perforations, and is used to prevent the inside plate from being strained by pressure.

They are joined togetherat the top andbottom by rivets, solder, or otherwise, thus forming a double cylinder, thel bottom of which rests on the rabbet K', for the purpose of having a permanentrest or seat, that the same may stay in its place.

The grooves n 'n are-covered with one or more thicknesses of perforated metallic plate, as shown at U, g.

' The platform B has a central opening,`as shown ati B, terminating in the spout B', used for 'conducting X represents; the cylindrical rim, attached to the centre of the metallic plate U, and is used to support the core-cylinder S, which stands vertically over the centre of the follower Y.'

'When i n use, thisscylinder is secured to the rim X by means of the r'odlW..-fand' catches Z, to prevent its Y being displaced.

rlhe cylinder-'5S is vconstructed of the same kind of metallic plates as `the cylinder Q R, and the finer-perforated plate is placed upon the outside of the plate containing the larger perforations, which is necessary, because the pressure on the core-cylinder S is inward.-

Surrounding the follower Y is the -colla-r Z, composed of India rubber, leather, or other suitable material, used for the purpose of preventing the mu'shing over and fitting closely to the outside of the corecylinder S, and the inside surface of the cylinder Q R, for the purpose of preventing the escape of the contents of the cylinder upward, when subjectto a pressure.

At G is shown the plunger, in which is made the air-chamber G', which passes over the outside of the core-cylinder S. l v v The ange L', on the lower part of the plunger, ex-

Vtends from the air-chamber to the inside surface of the cylinder Q R, and, when in operation, rests on the upper surface of the follower F', for the purpose of forcing downward the contents of the cylinder Q R.

D represents the standards, in which are cut the slots E, for the purpose of guiding the arms F, which are attached to' the upper part of the plunger IG, and forced down by means of the shaft I and rope or chain H, attached to the `arms F and shaft I, on each side of the press, which shaft I passes through horizontal bearings in the frame A, and to the upper portion of this frame is firmly attached the lower 'part of the standards D.

At J is shown the common lever and rachet-wheel K, by means of which the shaft I is loperated.

The weight 'c is hung on the opposite end of the lever, for the purpose of securing an even and steady pressure.

of the core-cylinder S, and pressed down upon the"\- mush-sugar; then place the ange L', of the plunger G, on the follower F', which will allow' the core-cylinder S to enter the air-chamber G. A

It will be seen, from this description, that in forcing the plunger G downward by means of the lever J, as abovedescribed, the molasses contained in the mushsugar will be driven through the perforations in the cylinderQ R, and conveyed, by the rim C, through the spout B', into the receiving-pan L. At the same time the molasses in the central portion of the cylinder Q R will be pressed through the perforations of the corecylinder S, and pass out through the grooves 'n n. and

the opening in the follower Y, and conveyed, by the grooves upon the conductors 0 N, into the receivingpan L.

'The air contained in the chamber G furnishes the required pressure to prevent the grooves u n from clogging, and forces the molassesl entirely clear from the inside of the core-cylinder S.

When the molasses has been pressed out of the sugar, the fall-leaf conductor O may be let down by turning the buttons P, as shown by the dotted lines 'J, which will permit the sugar in the cylinder Q R t0 pass into the sugar-receiver M, which sets directly under the opening in the platform B, and the opera tion is completed.

Having-thus described my invention,

I claim as new, andr desire to secure by Letters Patentl. The follower Y, supporting the conical perforated plate U and the core-cylinder S, constructed `and arranged to operate in the manner substantially as set forth.

2. Ihe' general arrangement of the cylinders Q R, conductors O N, follower Y, core-cylinder S, and airchamber G', constructed to operate substantially as specified.
